So, I often work with office files, but with Excel documents I work more frequent. And consequently I had a lot of types of problems with such files. Once I had an very complicated issue. To be more precise some my xls files were lost. To my good fortune I got a solution - *snip*. It resolved my issue for seconds and completely free of charge as I kept in mind. What is more I knew how the software solved problem with corrupted files in Microsoft Excel format and repaired Excel-unable to read file.
